Header-Only Libraries
Header-only libraries are C++ libraries where all the implementation code is contained within header files, eliminating the need for separate compilation and linking steps. They are typically distributed as a set of header files that users can directly include in their projects, making them easy to integrate and use. This approach simplifies dependency management and reduces build complexity, especially in cross-platform development.
Developers should use header-only libraries when they need lightweight, easy-to-integrate solutions for tasks like JSON parsing, logging, or mathematical computations in C++ projects. They are ideal for rapid prototyping, small to medium-sized applications, or when avoiding complex build systems is a priority, as they require no compilation and can be included directly with minimal setup.
